Abstract We reported an asymmetric supercapacitor technology where RuO2/TiO2 nanotube composite was used as positive electrode and the activated carbon as negative electrode in 1 mol/L KOH electrolyte solution. The electrochemical capacitance performance of the asymmetric supercapacitor was tested by cyclic voltammetry, electrochemical impedance spectroscopy and galvanostatic charge-discharge …
Abstract. The capacitive deionization (CDI) technology using different activated carbon electrodes was investigated to desalinate. The effect of specific surface area and pore structure of the activated carbon electrodes on the amount of ions removed in CDI was demonstrated. A highly mesoporous activated carbon (ACk2) was chosen to study desalination performance in detail. It is found that …
Abstract. Meso–macroporous TiO2 ceramics were obtained based on a two-stage ceramic membrane jet-flow emulsification and the influences of the triblock copolymers on the process are discussed in this study. The two α-Al2O3 ceramic membranes with average pore sizes of 0.5 and 1.6 μm were used to control the structure of nonaqueous emulsions. Polyethylene oxide (PEO)–polypropylene oxide…
Abstract. Ethanol decomposition was studied over Ni/Al2O3 catalysts with different Ni loadings (10–90 mol%) at temperatures between 500 and 800 oC to produce hydrogen and multi-walled carbon nanotubes (MWCNTs) at the same time. The hydrogen production increased with increasing temperature and Ni loadings. However, both the quality and the quantity of the nanotubes formed at the relatively…
Abstract. The co-production of hydrogen and carbon nanotubes (CNTs) from the decomposition of ethanol over Fe/ Al2O3 at different temperatures and feeding rates of ethanol was investigated systematically. The results indicated that Fe/Al2O3 was a quite active catalyst for the co-production of hydrogen and CNTs and that its activity and stability depended strongly on the Fe loading. Among al…
Abstract A simple and inexpensive approach to synthesizing mesoporous Fe3O4 is developed by using citric acidassisted solid thermal decomposition of ferric nitrate. The structure and magnetic property of mesoporous Fe3O4 were characterized by XRD, FT–IR, N2 adsorption–desorption isotherms, TEM, and vibrating sample magnetometer. It was shown that the decomposition of citric acid result…
MicroRNA (miRNA) has emerged as an important regulator of gene expression in plants. 146 miRNAs were identified from apple (Malus domestica cv. Golden Delicious) by bioinformatic analysis and RNA library sequencing.From these, 135 were conserved and 11 were novel miRNAs. Target analysis predicted one of the novel miRNAs,Md-miRLn11 (Malus domestica microRNA Ln11), targeted an apple nucleotide-b…
